Anemia is a condition in which blood has a lower-than-normal amount of red blood cells or hemoglobin. [1] Anemia in pregnancy is a decrease in the total red blood cells (RBCs) or hemoglobin in the blood during pregnancy. Anemia is an extremely common condition in pregnancy world-wide, conferring a number of health risks to mother and child. [2]
During the first 3 months of pregnancy, the main form of hemoglobin in the embryo/fetus is embryonic hemoglobin, which has 3 variants depending on the types of subunits it contains. The production of hemoglobin F starts from week 6, but it's only from 3 months onwards that it becomes the main type found in fetal red blood cells. [ 4 ]
Infants, toddlers, and pregnant women have higher than average needs. Increased iron intake is also needed to offset blood losses due to digestive tract issues, frequent blood donations, or heavy menstrual periods. [74] Iron is an essential part of hemoglobin, and low iron levels result in decreased incorporation of hemoglobin into red blood cells.
Pregnancy and childbirth are other risk factors for iron deficiency, because the fetus will absorb a significant amount of iron in the body. ... and their hemoglobin is dangerously low, a blood ...
In women, iron deficiency anemia has also been linked to mortality during pregnancy, lower birth rates, difficulty with milk production and possible lower IQs in children if the iron deficiency ...
Iron-deficiency anemia is anemia caused by a lack of iron. [3] Anemia is defined as a decrease in the number of red blood cells or the amount of hemoglobin in the blood. [3] When onset is slow, symptoms are often vague such as feeling tired, weak, short of breath, or having decreased ability to exercise. [1]
HbF/Fetal (α 2 γ 2) dominating during pregnancy and reducing close to zero a few weeks after birth; HbA (α 2 β 2) Adult hemoglobin, present in small quantities during pregnancy; Adult. HbA (α 2 β 2) comprising approximately 97% of adult hemoglobin; HbA 2 (α 2 δ 2) comprising approximately 3% of adult hemoglobin
Pregnant women: 11 to 14 g/dL (110 to 140 g/L, or 6.83 to 8.69 mmol/L) (9.5 to 15 usual value during pregnancy) [93] [b] Normal values of hemoglobin in the 1st and 3rd trimesters of pregnant women must be at least 11 g/dL and at least 10.5 g/dL during the 2nd trimester.
